Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 79 }$ to precision 5.
Roots:
$r_{ 1 }$ $=$ $ 29 + 55\cdot 79 + 60\cdot 79^{2} + 44\cdot 79^{3} + 9\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 2 }$ $=$ $ 36 + 42\cdot 79 + 64\cdot 79^{2} + 11\cdot 79^{3} + 73\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 3 }$ $=$ $ 43 + 36\cdot 79 + 14\cdot 79^{2} + 67\cdot 79^{3} + 5\cdot 79^{4} +O\left(79^{ 5 }\right)$
$r_{ 4 }$ $=$ $ 50 + 23\cdot 79 + 18\cdot 79^{2} + 34\cdot 79^{3} + 69\cdot 79^{4} +O\left(79^{ 5 }\right)$
